2003 Ford Crown Victoria P0453 Check Engine Light After Fuel Pump Replacement
In February 2018, I had my 2003 Ford Crown Victoria's fuel pump and filter replaced at an auto repair shop. At the time of service, there was no check engine light on. However, shortly after receiving the vehicle back, a Check Engine Light activated with diagnostic code P0453. I'm concerned whether this issue is directly related to the work performed during the fuel pump replacement. Since my state requires an emissions inspection (eCheck), I need to know how to resolve this code and whether the repair shop is liable. Could replacing the fuel pump have caused or triggered a P0453 fault? Should I take the vehicle back to the shop for correction, or is this a known issue after fuel pump replacement? Any advice would be greatly appreciated.
It's important to confirm whether the repair shop installed a genuine Ford fuel pump or an aftermarket unit—this detail can significantly impact the outcome. Consider taking your vehicle back to the shop and asking them to diagnose and fix the issue. If they are reputable, they may resolve it at no cost.
